摘要

本論文主要利用可程式控制器(Programmable Logic Controller，PLC)之控制方法作為控制的主要核心。在自動化設備方面，為了配合奶油工廠自動化的需求，設計並製作兩種自動化設備作為工廠自動化生產之目標，再配合可程式控制器與電控元件的感測及驅動，來完成工廠自動化設備之設計與開發。另一方面，也針對沖模研磨機問題加以設計分析，為使其輸入介面與可程式控制器達成通訊的作用，自行設計了一組可傳輸資料的人機介面，來當作研磨機之輸入及顯示介面。此外，沖模研磨機為達到較精密研磨的目的，必須考慮砂輪磨耗所造成之研磨誤差量。為減少額外使用感測器，本論文利用馬達之電流與砂輪磨耗的關係，推導出預估之研磨補償模型，並以可程式控制器執行研磨時之砂輪磨耗補償控制。經實驗驗證，所推導之研磨補償數學模式與實驗頗為吻合，且磨耗補償之效果良好。

This thesis uses programmable logic controller (PLC) as the principal control unit for automation. In the automatic equipment, designing and manufacturing two automatic equipment is to be the target of the factory automatic production, and is to finish the design and build of the automatic equipment for match up the factory requirement. Using PLC and some control component is to be the controller, sensors and actuators. This thesis design and analysis the die-grinding machine is another subject to investigate. A man-machine interface, which communicates with the PLC, is developed to input and display the data of the die-grinding machine. For the purpose of precise grinding, the grinding error coming from the wear of grinding wheel in grinding process needs to be considered. Without using extra sensors, the relation of the motor current and the wear of grinding wheel is studied and derived with a prediction model. Such model associated with the PLC is expected to compensation the error. From experimented testing, the modeling is accurate enough, and the PLC control scheme is able to automatically compensate the wear of grinding wheel.
